Castle Geyser erupts, reaching 60 to 90 feet in height and lasting 20 minutes.  While Castle Geyser has a 12 foot sinter cone that took 5,000 to 15,000 years to form, it is in fact situated atop geyserite terraces that themselves may have taken 200,000 years to form, making it likely the oldest active geyser in the park. Upper Geyser Basin, Yellowstone National Park, Wyoming
